Compute SHA256 of bytes or strings.
This library is deprecated. If you think it's important to maintain this library, please submit an issue and the case will be consider or the repo / ownership will be transferred to you. Viable alternatives:
npm install --save sha256
Note: when Node.js is detected, the Node
Crypto component is used instead of re-implementing the SHA256 hash logic.
There are two methods, one for computing the hash of the input, and one for double-hashing it:
; // "2cf24dba5fb0a30e26e83b2ac5b9e29e1b161e5c1fa7425e73043362938b9824"sha256; // "d7914fe546b684688bb95f4f888a92dfc680603a75f23eb823658031fff766d9"
Input is either an array of bytes or a string. String are always interpreted as binary data; if you have a hex-encoded string of data to parse, first convert it to a binary string or array of bytes.
Output by default is a hexadecimal-encoded string. Other options are an array of bytes, or a binary-encoded string:
; // "2cf24dba5fb0a30e26e83b2ac5b9e29e1b161e5c1fa7425e73043362938b9824" <= Hex-encoded; default; // [44,242,77,186,95,176,163,14,38,232,59,42,197,185,226,158,27,22,30,92,31,167,66,94,115,4,51,98,147,139,152,36] <= Array of bytes; // ",òMº_°£&è;*Å¹â\§B^s3b$" <= Binary-encoded string
Unit tests are written in Mocha. To run the test suite, checkout the git repository, and from within the base folder run:
$ npm install --dev$ npm test
